Method for ultrasonic dissection of tissues
View Patent ↗Methods for dissecting tissues are provided. The methods comprise selecting a tissue site comprising dermis and subdermal fat connected to the dermis, and applying ultrasonic energy to the tissue to remove at least a portion of the subdermal fat from the dermis, wherein the ultrasonic energy is applied to minimize damage to the dermis.
1. A method for dissecting tissues, comprising:
selecting tissue removed from a cadaver or animal source, the tissue comprising dermis and subdermal fat connected to the dermis;
applying ultrasonic energy to the removed tissue to remove at least a portion of the subdermal fat from the dermis, wherein the ultrasonic energy is pulsed, and wherein the ultrasonic energy is applied to minimize damage to the dermis; and
cooling the dermis while applying the ultrasonic energy, wherein the cooling is performed by laying the dermis upon a solid supporting cold surface.
2. The method of claim 1 , wherein at least a portion of the dermis is not heated to greater than 50° C.
3. The method of claim 2 , wherein the entire dermis is not heated to greater than 50° C.
4. The method of claim 1 , wherein the ultrasonic energy is applied with a blunt probe.
5. The method of claim 1 , wherein the ultrasonic energy is applied at a dermal-fat junction.
6. The method of claim 1 , wherein the ultrasonic energy is applied to cut, melt, or emulsify fat.
7. The method of claim 1 , wherein the dermis is human dermis.
8. The method of claim 1 , wherein substantially all the subdermal fat is removed from the dermis.
9. The method of claim 1 , wherein the cooling is performed by contacting the dermis with a cold surface applied to an entire surface of the tissue site.
